This is not uncommon when dial feet are damaged.
The easy way is dial dots: Dial Adhesives for Watch Repair
But you’re right that glue is both more and less permanent in all the wrong ways. You can also do soldering which is probably the best method. The good news is these dials aren’t especially pricey so it’s okay to buy a few more and practice.
For awareness, one of my watches the dial (from another company) didn’t have enough friction to stay in. It rose slightly and stopped the watch after a drop. Easy to fix; pull the movement back out and reattach, this time using some scotch double sided tape on the movement ring. But the movement of the hour hand left a slight scratch I can see under the magnifier. So keeping it secured is important. And yes, aligning it so it looks right to you is also important (and maybe a better reason for the dots, since you can more easily remove it and retry.)
Fortunately this is a kit designed for building so I totally recommend giving it a swing and making the worlds only left-handed DWC!! I’ve had to rebuy parts from mistakes and it’s not really an issue.
